Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive bundling indicators for a plurality of downlink transmissions and corresponding downlink assignment indicators associated with the bundling indicators, determine a demodulation reference signal (DMRS) bundling configuration based on the bundling indicators and the corresponding downlink assignment indicators, and process demodulation reference signals according to the DMRS bundling configuration. A wireless device may also receive bundling indicators for a plurality of downlink transmissions, determine a demodulation reference signal (DMRS) bundling configuration based on the bundling indicators and a gap between successive transmissions of the plurality of downlink transmissions, and process demodulation reference signals according to the DMRS bundling configuration.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for managing uplink power control in accordance with priority-specific beta factors. An example method for wireless communication performed by a user equipment (UE) generally includes determining a value of a beta factor based on a priority level of uplink control information (UCI) to be transmitted on a physical uplink shared channel (PUSCH); and transmitting the UCI on the PUSCH with transmit power determined based, at least in part, on the value of beta factor. Another example method performed by a UE generally includes deciding, when the UE is configured to perform demodulation reference signal (DMRS) bundling across PUSCH repetitions, whether to prioritize the DMRS bundling or transmission of UCI multiplexed in one of the PUSCH repetitions; and transmitting the PUSCH repetition with the multiplexed UCI in accordance with the decision.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method, performed by a network node, for selection of uplink control information (UCI) transmission format, comprises determining whether to use a coherent transmission; upon determining to use a coherent transmission, selecting a coherent transmission format for UCI transmission. Upon determining not to use a coherent transmission the method further includes determining whether to use an orthogonal sequence: upon determining to use an orthogonal sequence, the method includes selecting a non-coherent transmission format with an orthogonal sequence for UCI transmission; upon determining not to use an orthogonal sequence, the method includes selecting a non-coherent transmission format with a non-orthogonal sequence for UCI transmission. The method further includes using the selected format for UCI transmission. For example, a base station may send the selected format for UCI transmission to a UE, or a UE may select and use the UCI transmission format.

Abstract: Aspects of the disclosure relate to wireless communication using channel state information (CSI) correlation information for determining the validity of a CSI report. A user equipment (UE) can determine the CSI correlation information based on reference signal resources scheduled for measuring CSI and interference on a channel between the UE and a network entity. In some aspects, the CSI correlation information can be determined based on channel correlation information and/or interference correlation information.

Abstract: A base station may transmit a set of CSI-RSs corresponding to a set of ports of a UE and the UE may perform a set of CQI measurements on each port and across each sub-band. The UE may select, for each CSI-RS resource that the UE measures, a set of M worst CQIs and may select a best CSI-RS resource based at least in part on a corresponding set of M worst CQIs for the CSI-RS resource. The UE may report the M worst CQIs for the selected CSI-RS resource. Alternatively, the UE may select, for each CSI-RS resource that the UE measures, a set of M worst CQIs and may select a worst CSI-RS resource. In this way, the UE enables the base station to select a DMRS port and/or an MCS to use for communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a multiplexed message including first information with a first priority and second information with a second priority, wherein the first priority is higher than the second priority. The UE may transmit the multiplexed message using a particular cyclic shift of a particular cyclic shift set of a plurality of cyclic shift sets, wherein the particular cyclic shift set is based at least in part on the first information and the particular cyclic shift is based at least in part on the second information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on one or more decoding outcomes associated with one or more downlink communications, a resource, of a set of candidate resources, to use for transmitting a channel state information (CSI) report. The UE may transmit the CSI report via the resource. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor for two or more messages from a base station. The UE may transmit, to the base station, at least one bit (e.g., in first stage uplink control information (UCI)) that is based at least in part on combined acknowledgement feedback associated with the two or more messages and that indicates a subset of possible decoding events associated with the two or more messages. In some aspects, the UE may further transmit at least one additional bit (e.g., in second stage UCI) that is based at least in part on the combined acknowledgement feedback and that indicates a different subset of possible decoding events associated with the two or more messages. Numerous other aspects are described.
